I've created a gridview dynamically in code behind. In the gridview one of the column is a having a checkbox control in it. User can select 1, 2 or any no. of rows he / she wants for further processing. Upon selection of a row, I'll do some processing and user will select another row as per their requirement.

My question is How can I know on which row user has clicked checkbox. I need to know this because each row will be having different value for processing.

Also when I click on any of checkboxes (AUTOPOSTBACK=True), the checkbox field got disappeared.

Thanks in advance ...
